Not quite actually - in case of splitting the problem does not stem from 
the long segments but from the fact that you split one polygon but do 
not split the edge of the adjacent one at the same time.  If you'd do 
that the edges could have any length, they would still fit after the 
reprojection (although you could get intersections between the actual 
coastline and the splitting lines).
